To all whom it may concern:

Be it known that l, EmmAnnnnson, a citizen ofthe United States ofAmerica and a resident of New York, county and tate of New York, haveinvented certain new in 'TurbineEngines, of which the following is aspecification, reference being had to the accompanying drawings, forminga part thereof. My invention relatesto improvements in turbines, and itsobject is to provide a simple 15 is a sectional end elevation of one ofthe rotor. An inverted plan view of the nozzle block is shown in Fig.16. One of the partition plates of the rotor is shown in detail in rotorblades is shown in vation in Fig. 18. Another of the rotor blades isshown in side elevation and inplan view in Fig. 19, and a rotor blade ofanother form is shown in plan view in Fig. 20.

Like characters of reference designate correspondingparts in all thefigures.

The turbine shown in Figs. 1 and 2 comprises an annular casinglO formedof two parts 11 and 12 bolted together-as at 13. To these parts aresecured the bearings 1d--14 of the rotor shaft 20. Secured to the rotorshaft is a disk 21 upon whichis carried the rotor ring. This rotor ringis built up between two that annular side plates 22 and 23 and a rimflange 24;. Between these parts are secured at equal intervals thetransverse partition plates 25, by means of lugs 26 whichfit into holesin the side plates 22 and 23 and a lug 27 which fits into a hole in therim flange 24:. In each of the compartments formed between the sideplates by these transverse partition plates and secured to the plateside 23 is a wavy or corrugated ro- 1 will describe my invention in thefollowing specification, and then point out the novel features thereofin appended claims.

Referring to the drawings: Figure 1 is a sectional side'elevation of asimple form of Fig. 2 is an end elevation of the apparatus which isshown in Fig. 1 with certain parts broken away, and some of the partsshown in section in order to illustrate clearly the construction. Aportion of the rotor is shown in transverse sections in Figs. 3 and aretaken at right angles to each other, the section in Fig. 3 being takenon the line 3-43 of Fig. 4 and the section in Fig. 4 being taken on theline H of Fig. 3. One of the partition plates which is used in the andin plan in edge view 6. Fig. 7

figures is shown Figs. 5 and view respectively in over as at 31. 28 is apin secured to the plate 23. to strengthen and support the part 31 ofthis rotor blade. is a shorter wavy rotor blade 32 which is parallelwith the wavy part of blade 30 and which is secured to plate 22. Anintermediate wavy rotor blade 33 is between the blades 30 and 32 andparallel therewith. This one is of the same size and shape as the blade'32 but is provided on one of its edges with lugs 34 which fit intoholes 29 in the adjacent partition plate 25 and on its opposite and Fig.8 a sectional edge view of the same. Another ofthe rotor blades isshownin plan view in Fig. 9; Certain parts of another. form ofturbineembodying this same invention, is shown in sectional end view in Fig.10. A turbine which is made according to my invention and which embodiesa development of the sanie idea, is illustrated in sectional sideelevation in Fig. 11. The same. turbine is shown in end elevation inFig. 12 with some of its parts broken away and with some of its partsshown in section. etails of the construction of the turbine of. Figs. 11and 12 are shown in the succeeding figures of which Fig). 13 is atopplan view of one of the nozzle looks with a portion of ply, isconnected.

nozzle blocks and of an adjacent part of the tor blade 30, the outer endof which is bent I the nozzle blocks 17, each ofwhich is divided byplates 18 into a plurality of outward flow expansion nozzles, and eachof which is provided with a valve-controlled port 19 communicating withthe chamber 15. Before specifically describing the other figures of thedrawings, I will explain the operation of the form of turbine which isillustrated in the first nine figures of the drawings. Motive fluid,such for example as steam, is admitted through the ports 19 into thenozzle blocks and is delivered under practical-1y no pressure but athigh velocity from the expansion nozzles into the rotor ring. Here itsdirection is changed from side to side as it passes through the zigzagchannels formed between the wavy rotor blades. At each'deflection of itspath some of its velocity is given-up and is changed into kinetic energyas it causes the rotor and its shaft to be driven. After the motivefluid leaves the ends of the zigzag paths at theouter edges of the rotorblades 32 and 33 it is deflected over and backward by the curved part 31of the rotor blades 30. These parts are so positioned that their effectupon the motive fluid causes a reaction which is a further drivingimpulse. The fluid is then discharged at low velocity into an enlargedportion 36 of the casing from which it passes through an exhaust pipe 37to condensers or to the air. This turbine although of extremely simpleand substantial construction is capable of developing high power withbut little consumption of motive fluid. In other words, it is anapparatus of high efficlency. a

In Fig. 10 the nozzles 38 are on the outsideof the ring arranged todirect the motive fluid inwardly and the rotor blades are reversed inposition. The operation of this form of turbine is otherwisesubstantially the same as that which has been described. A furtherdevelopment of the same idea is embodied in the turbine which isillustrated in the remaining figures of the drawings.

This, as may be seen from Figs. 11 and 12, comprises a casing of twoannular parts which in. this case are designated by 41 and 42 whichsupport the bearings 44 for the rotor shaft 50. The casing part 41 isconstructed to form an annular chamber 45 with which the motive fluidsupply is connected at 46. Aflixed to this art of the casing at equallyspaced interva s, are the nozzle blocks 47 which are in communicationwith the chamber 45 through ports 49, all

but one of which is valve-controlled. Referring to Figs. 13, 15 and 16,it will be Seen that these nozzle blocks are each constructed to formtwo passages, the first of which, designated by 40, is a narrowexpansion nozzle adapted to direct the motive fluid inwardly into therotor ring. The other passage is curved and comprises an parts of therotor. The partition plates 53 are constructed with cars 54 projectingfrom their opposite edges. These ears fit into narrow recesses in theside plates 51-52 and after they are in place with the rotor bladeswhich I will describe presently, are supported in the side plates bymeans of bolts or rivets 55 which pass through the side plates and drawthem together against the edges of the division plates. As in the otherstructure, there are between. adjacent partition plates three rotorblades. One of these, designated by 60, has end. flanges 61 which fitinto transverse slits in the rims of the side plates, a wavy portion 62,and another part 63 bent on a longer curve. It also has lugs 64projecting from'its opposite edges which fit into holes 56 in thepartition plates. Another, 65, of the rotor blades has a straightportion 66 and a wavy portion 67 and from. its edges project lugs 68which fit into holes 57 in the partition plates. The third rotor blade 70 has a straight portion 71, a wavy portion 72, and its end is bent backas at 73. From 1ts edges project lugs .74 which fit into holes 58 in thepartition compartments between the side plate 51 and the part 66 ofrotor blade 65. It then passes through the passage formed between theparallel wavy parts. of the rotor blades 60 and 65 where it is deflectedfrom side to side,

giving up some of its velocity and driving the rotor. When it reachesthe end of the short rotor blades 65 and 7 0, it is allowed to expandand is at the same time turned back by the part 63 of blade 60, givinga'further drivingimpulse to the rotor. It then enters the nozzle block47 at the port 43 and in the block is turned again and directed throughexpansion nozzle 48 into the rotor. This time-it enters the two passagesbetween the blades60 and 65, and 65 and 70, where it is again deflectedfrom side to side after WhlCh it is again deflected by the part 63 ofblade 60, this time escapin into the chamber 75 within the casing, romwhich it is discharged through the exhaust 76.

The operation described 'may be perarallel with one formed in eithercase with the nozzles in i one of the nozzle bloclzs. .0bviously morepower will be developed when thevalves to mas-are.

more than one nozzle block are opened, and

more or lessof these nozzle blocks-may be,

made active according. to the amount of power desired.

It is to be noted that both of the turbines which have beendescribed,while difi'ering in construction, operate onythe same principle,although in the second formof apparatus the 'motivefluid is passed twicethrough the rotor.
